v To all whom it may concern:

Be it known that I, Ln VERN Fox, a citizen of the United States of America, residing at Hutchinson,'in the county of Reno and State of Kansas, have inventedcertain new and useful Improvements in Gasolene Motor-Cars, of which the following 7 is a specification, reference being had therein to the accompanying drawing.

My invention relates to railway cars, and has for its object the improvement of motor cars, with particular reference to so-called gasolene motors by which are meant those motors which employ internal combustion engines of all types. The term is sometimes used to-include compressed air or steam cars using gasolene for fuel, although such motors are not subject to the limitations, and do not require the same refinements of mounting and connection as the internal combustion motors. For example, a steam engine may be and has been mounted upon the axleof a car, with auxiliary suspension and intermediate gears, connecting the piston with the axle; and compressed air motors in so far as they are employed, can be mounted in a similar way. An example of such mounting is found in USS. Letters Patent 801,448, anted October 10, 1905, to C. Fellner. It would obviously be impracticable for an internal combustion engine which requires a fly wheel, change gears or the equivalent, and other auxiliary parts not required by a vapor engine.

In standard railway practice, it is well understood that careful provision must be\ made for relative motion between a car body and the wheels or trucks, between different "parts of the car body, and between any auxillary parts mounted upon and requiring connection between the movable parts. Thus for example it is necessary to provide both for and against la eral motion of the body and also'swinging motion of the body upon and aroundthe truck bolsters as well as a rotary motion on the king bolts or equivalent parts; Transmission of power from an element mounted on a car body to another element mounted on a truck axle or vice versa, has always been attained with more or-less difliculty on account of the complex motions met in operation which include relative longitudinal motion as well as the others mentiond. Attempts have been made to compensate f0 this by using oblique transmission shafts with or without compensating joints, the idea being that either longitudinal or vertical motion of the body would be taken up by angular displacement around the axle of the connecting gears. This has not proved successful in practice, however,

and one'object of my invention is to meet this condition by efiecting a rigid distance connection between the power plant and the axle, while at the same time permitting a universal motion in every other respect. In order to render the transmission eflicient, which is impossible with a normally oblique shaft, and at the same time to preserve the advantages of mounting. the power plant on the car body, I assemble and mountthe complete power plant as a unit upon a rigid auxiliary frame and suspend or hang the same beneath the car body, approximately at the level of the truck axles or truck frames, so that the power transmission elements are normally horizontal and longitudinally in alinement between the centers of the trucks.

In order to accomplish fixed longitudinal relation between the power plant and the driven axle, I employ a connecting or torsion rod containing universal motion, and extending from the gear case or gear mounting on the axle to the frame of the power plant itself. In systems-previously proposed so far as I am aware, torsion rods or'elements of this character have always been secured to the fixed parts such as the truck frames, or .to the body. Obviously such arrangements are open to the fatal ob ect on that they bear no relation to thepower plant and serveonly to keep the gear supports or bearings from turning around the axle.

By providing universal joints in my propeller shaft by which it becomes; a umversally flexible shaft, I find that practlcallyall the motions which take place. in operation are compensated for by slight variations from normal direction of the transmission line, while the engagement and position of gears, and the distance relation between the parts is never affected. This applies to the rounding of curves, sudden acceleration and deceleration, road shocks, and the like.

motion. In order to render this result certain as well as protect the power plant itself from certain lateral shocks, I provide a mode of suspension with lateral braces which will be specifically described and claimed hereinafter.- It will be noted, however, that fore and aft the longitudinal bracing is not so important, so long as there is a sufficient factor of safety allowed in figuring the strength of the suspension devices.

In connection with the suspension of the power plant, and its horizontal connection to the axle, it should be noted that in order to produce symmetrical compensation, the power plant and connections must be substantially central, and the shaft and gear connections must be between and not outside of the wheels of the truck or trucks. A sysa part of the invention. iside bars to the rear of the radiator is the bed plate 6, carrying the engine 7, there betem in which it was attempted to drive from the body to the end of the axle would be obviously impracticable if not entirely inoperative, because of the greatly multiplled motion of the ends of the axles as the trucks turn in rounding curves and the like.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my power plant and connections, attached beneath a car.

Fig. 2 is a plan view of the same looking from above.

Fig. 3 is a sectional view on an enlarged scale of the gear box on the driving axle and connecting parts. I

Fig. 4 is a detail view of one of the hangers shown in Fig. 2.

In the drawings, 1-2-34 represents the chassis, formed of structural metal shapes of the type usually employed. in automobile construction, which I provide as the supporting framework for my power plant. At the front end of the chassis is mounted a radiator 9, which, however, is not in itself ing indicated three pairs of cylinders, with out any valve or other attachments. It is to be understood that the drawing of these,

parts is diagrammatic, as the details vary with the type of engine employed, and can be supplied by a'skilled engineer, without invention.

10 designates the fly wheel and coneclutch, 11"a couplin for the stub shaft on the propeller side of the clutch. 12 is the transmission shaft extending from the coupllng to the transmission gear case 14, and having inserted in it a universal joint 13. The transmission ears 14 in their case, are

supported on para el bridges 4 and 5. From 8 the rear end of this case the propeller shaft 16 extends to the gear case 28 on the axle 19 of the car truck. The shaft 16 is provided with two universal joints-15 and 17, and the gear case is provided with a torsion rod 29, having a turn-buckle 30 and a ,universal mo- Bridged across the tion 31, through which it is connected at 32 to the end member of the chassis.

The operation of this system, as thus far briefly described, is readily understood. Power is transmitted from the engine in such ratio as may be determined by manipulation of the transmission gears, through the propeller shaft and the intermeshing gears in the box 28, to the axle 19, and this may be direct or reversed, according to the position of the transmission gears. found that to exert power upon one pair of wheels alone is not efficient, however, because a slight film of water. or ice onthe track will cause spinning and immediate loss of tractile effect. To avoid this, and prevent the first pull of the engine from overcoming the spot adhesion of the wheel rims to the rails, I couple the two axles of the truck together, in the manner shown. The axle 19 carries the sprocket 25, and the axle 21 carries a sprocket 26. These two sprockets are reciprocally driven by means of a chain 27. Sprockets and chain, as well as the ends of the axles, are housed in a casing 33, provided with openings fitting upon the axles, and which may be filled with oil if desired, but is primarily intended to keep dust and grit out of the chain.

Referring to Fig. 3, the gearbox 28 is preferabl a casting made in parts bolted together, ut may be integral and cored out, with a hand-hold provided with a suitable cover bolted in place, and large enough to give access to the working parts and permit their removal if necessary. The universal joint 17 of the propeller shaft 16 is con nected withthe ears in this box through a short shaft 18 tted witha sleeve 34 and race rings 35 and 36 for ball bearings 37 and 38. The outer race rings for these ball bearings are made a driving fit in a cylindrical casting 39, flanged at 40 to receive bolts 41 which secure it to the casing. The end of this ,casting is closed by a cap ring 42, carrying a gland 43 of any usual or preferred type to retain oil. This cap ring is locked against turning by means of a sprin latch '44 taking intoa slot in theed e of the cap, which therefore cannot back 0%. On its inner end the shaft 18 carries a bevel pinion with the teeth of a bevel gear 47, cast with.

a large central opening 48 which takes around one end of the sleeve 49, the inner flange of the gear resting against an exte-' nor flange 50 of the sleeve, to which it is sec ured by rivets or bolts 51.

J The sleeve 49 is keyed to the axle 19, and may be cast in two parts for ready applicatlon. It 1s shown with a through bolt 52 securmg it on the shaft, but this is a detail I for the torsion rod is to the fairly contained unit and hang forming no special part of my invention by itself. At each end of the sleeve are end thrust bearings 53 and 54;v and outside of these are the brasses or Babbitt metal liners 55 and 56. The shaft openings in the easing are closed by cap rings 57 and 58, held ground faces by bolts 59, 60, 61, 62 and with interposed packing rings 63 andG-l to retain the oil.

It will be observed that the .casing has an enlargement 65 giving it a conical shape with the extension around the shaft 18 forming an intersecting cylinder. Not only has it een found easy to cast this shape, but it possesses certain elements of strength which particularly adapt it to resist the strains to which it is subjected in practice, without fracture, though not containing a large mass of metal. It runs filled with oil, and requires practically no attention so Long as the oil lasts. In this Fig. 3 the attachment 66 shown formed upon the body of the casing, but if desired it may becast upon the cylinder 39, or may be formed separately and attached by means of the bolt 41.

I am aware that it has heretofore been proposed todrive railway coaches of the poses, have been secured beneath car bodies.

But I believe it to be novel and original with me to form the power plant as a selfcar, practically lining it up with the driven axle, so as to relieve all parts of strain, and especially to prevent undue normal angularity of the propeller shaft. To secure my purpose, I first mount the entire power plant on the chassis 123456, and then suspend the said plant as a unit by means of the brackets 8, or equivalent hangers. It will be observed that these-are provided with verticaland diagonal members. The vertical members carry the weight, and the diagonal members take the torsional strain transmitted from the crank shaft, and also take up all side strains due to lateral motion of the car body.

The gasolene motor car equip ed with the power unit thus described has een completely reduced to practice and inoperation on the Anthony and Northern Railway of Kansas, for a considerable period. Its performance, operating expense, and cost of maintenance are better. than those of any. other of which I have siderable percentage in every case.

It should be understood .that the part shown in Fig. 3 are constructed in accord1 ance with the proper and usual practice in construction shops. For example the sleeve 48 may be formed in two parts, held together at one end by one or more bolts 52, at

it beneath the knowledge by a con bind the two halves of the sleeve efi'ectively as one. lfn any case the keys shown on opposite sides of the shaft must be provided with suitable slots or key-ways in both axle and sleeve although when the sleeve is formed in two halves as described, the slots need not be as long as the keys themselves.

lit should be further understood that some changes may be made inthe specific construction and arrangement of parts heretofore described without departing from my invention, and that in the use of terms such as gasolene motor in the a pended claims, I intend to include all other forms and equivalents which present the same characteristics and require the same treatment.
